Dual output modules:
<1% pk-pk.
DYNAMIC LOAD TRANSIENT RESPONSE
A 25% step load change will result in an output deviation (overshoot or undershoot) of less
than 3% of nominal output voltage (150mV for <5V outputs, 400mV for the </= 5V 1000W
module). Output voltage will recover to within 1% of set value within 300
m
s (500us for the
</=5V 1000W module.) Slew rate not to exceed 1A/us.
DYNAMIC CROSS REGULATION
The effect of dynamic cross regulation on any fully loaded auxiliary channel for a load step
change of 25% from a 75% base value on the highest rated channel, at a slew rate not to
exceed 1A/us, shall be less than 0.1% for single output modules and less than 3% for dual
output modules. The summation of the individual module powers must not exceed the total
rated power of the UF1500. This measurement is to be performed with all other channels
loaded to 50% of rated load.
TEMPERATURE COEFFICIENT
The output voltage will change less than .02% per
o
C over the ambient temperature range of
0-50
o
C. (After 30 minute warm-up).
NO LOAD OPERATION
Operation at no load will not cause damage to the UltraFlex supply, however the output
voltages may be outside the regulation band. A 1 Ampere preload is required on the highest
rated output for a dual output module.
OVER TEMPERATURE SHUTDOWN
The power supply is self-protected against over-temperature conditions. A thermal shutdown
requires re-cycling of the input voltage to restore output. The fan will continue to operate
during thermal shutdown.
OPERATING ENVIRONMENT
The power supply is designed to meet the performance parameters defined above when
operated within the following conditions:
Temperature:
0 to 50
o
C; -20
o
C Start-Up, 30 Minutes to perform
within specifications.
Humidity:
10% - 90% Non-condensing
Altitude:
0 – 10,000 ft. Operating
The power supply will not be damaged during transit and storage when subjected to the
following conditions:
Temperature:
-40
o
C to +85
